A New Method of Modern Road Survey Technology and Safety Auditing

With the progress of science and technology, existing methods of surveying and safety auditing have been difficult to meet the increasing demands of people, so a new method is needed. First, by comparing and analyzing the advantages and disadvantages of different mapping techniques, we finally find that under the different demand conditions, the digital mapping technology which uses the UAV aerial mapping, total station, and 3D LIDAR on vehicle in collaboration with the GPS is more advanced, accurate, and practical. Then, with the method of HintCAD in collaboration with 3D Max to realize the digital visualization of road design, the designer can analyze the road design in 3D. Finally, a driving simulation is based on operating speed and human factors to audit the safety of road design, which can offer a truly people-oriented safety audit from the perspective of road users.
